"Could not find Oblivion.exe"

I'm trying to run my first Oblivion server. I'm not sure if what I've done so far is correct though. I just changed the settings in the .ini file, now the program looks for default.ess instead of default.fos (don't know if this is the correct method). I can see the server in vaultmp.exe and I've already Sync'd just in case. Now, when I try to join I get an error message saying, "Could not find Oblivion.exe".

I've already tried to copy the Oblivion.exe into the server folder but that didn't work. Any ideas on what to do?

Oh my God, I feel like moron. Sorry guys, false alarm. Mods please delete this thread. Sorry!
